Can you see how long a Facebook ad has been running?
Often, yes. In Meta Ads Library, active ads may show a start date or active status. RunningAds also shows start date and running days where that data is available.
Does a long-running ad mean it is profitable?
No. A long-running ad is not proof of profitability. It is a useful research signal that can help decide which ads are worth studying first.
How long should an ad run before it is worth studying?
A seven-day ad can be worth noticing, a thirty-day ad is a stronger signal, and a sixty to ninety day ad often deserves deeper review. The right threshold depends on the brand, budget, campaign type, and seasonality.
Can I use Meta Ads Library for free?
Yes. Meta Ads Library is a free official source for public ad lookup. The tradeoff is that research can be manual when comparing many ads or brands.
What is the fastest way to find long-running Meta ads?
The fastest workflow is to search a brand in RunningAds and review active ads with duration signals where available. Meta Ads Library remains useful for manual source checking.
Why do agencies care about long-running ads?
Agencies use long-running ads to prepare competitor examples, creative references, offer observations, and strategy discussion points. Duration helps them prioritize what to review.
